Effects of a Priori Liking on the Elicitation of Mimicry

Mimicry and prosocial feelings are generally thought to be positively related.
However, the conditions under which mimicry and liking are related largely
remain unspecified. We advance this specification by examining the relationship
between mimicry and liking more thoroughly. In two experiments, we manipulated
an individual’s a priori liking for another and investigated whether
it influenced mimicry of that person. Our experiments demonstrate that in the
presence of a reason to like a target, automatic mimicry is increased. However,
m [...]
Pedagogical Effect of Action on Arithmetic Performances in Wynn-Like Tasks Solved by 2-Year-Olds

Previous studies have provided evidence of interference due to a
language-default mode (i.e., the singular/plural opposition) in
2-year-old children when solving arithmetic problems using a traditional
onlooker method. However, an action-based method could help to bypass this
language bias. In particular, when an arithmetic problem is presented to the
children by the experimenter (onlooker mode) or realized by the children
themselves (actor mode), performances are better with the latter. Thus, an
experimental procedure based on “math i [...]
The Role of a Change Heuristic in Judgments of Sound Intensity

Leboe and Mondor (2008) demonstrated that participants will apply a
change heuristic when making duration judgments. In this
study we investigated whether participants would apply this same change
heuristic when making judgments about the perceived intensity of a
sound. In two experiments, participants were presented with two consecutive
sounds on each of a series of trials and their task was to judge whether the
second sound was louder or quieter than the first. In Experiment 1, participants
were more likely to judge sounds that increas [...]
Effects of Facial Identity on Age Judgments

According to current face recognition models, facial identity is processed
independently from other visually derived facial aspects, such as facial age.
Here we used a repetition priming paradigm to investigate the relationship
between the processing of facial identity and facial age. In Experiment 1,
participants made speeded age classifications for primed and unprimed faces of
famous celebrities. Performance was faster and more accurate for primed compared
to unprimed faces, which indicates that the processing of facial age benefits
fr [...]
Direct Access to Working Memory Contents

In two experiments participants held in working memory (WM) three digits in
three different colors, and updated individual digits with the results of
arithmetic equations presented in one of the colors. In the memory-access
condition, a digit from WM had to be used as the first number in the equation;
in the no-access condition, complete equations were presented so that no
information from WM had to be accessed for the computation. Updating a digit not
updated in the preceding step took longer than updating the same digit as in the
prece [...]
Recognizing and Predicting Movement Effects

It is not clear whether the critical features used to discriminate movements are
identical to those involved in predicting the same movement’s effects
and consequently, whether the mechanisms underlying recognition and anticipation
differ. We examined whether people rely on different kinematic information when
required to recognize differences in the movement pattern in comparison to when
they have to anticipate the outcome of these same movements. Naïve
participants were presented with paired presentations of point-light animated
ten [...]
Being on the Lookout for Validity
Recently, Sriram and Greenwald (2009) introduced a new IAT-like measure, the
Brief Implicit Association Test (BIAT). Because the BIAT is a new development,
empirical evidence for its validity is yet scarce. This comment focuses on two
possible approaches to validation research on the BIAT: (1) a pragmatic
correlational approach and (2) an experimental approach aiming at causal
understanding of the BIAT task. We argue that both approaches provide valuable
and mutually complementing evidence, but only experimental research can
conclusively [...]
Prime Proportion Affects Masked Priming of Fixed and Free-Choice Responses

Left/right “fixed” responses to arrow targets
are influenced by whether a masked arrow prime is congruent or incongruent with
the required target response. Left/right
“free-choice” responses on trials with ambiguous targets
that are mixed among fixed trials are also influenced by masked arrow primes. We
show that the magnitude of masked priming of both fixed and free-choice
responses is greater when the proportion of fixed trials with congruent primes
is .8 rather than .2. Unconscious manipulation of context can thus influence
b [...]
